How does Roman Catholicism define "the simplicity that is in Christ" found in 2 Corinthians 11:3?

Having just asked this question of Roman Catholicism, which included a fairly lengthy attempt at defining the "simplicity that is in Christ" (2 Corinthians 11:3) from a biblical perspective and, in response to an immediate comment, I would like to ask this: According to Roman Catholicism, what is meant by this phrase "the simplicity that is in Christ" which Paul was concerned that the Corinthian minds were being corrupted from? > But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. 2 Corinthians 11:3
